Hi,

I have files with the extension .GEO and .img ... the .GEO is DTM as I know and the .img is the raster file. Also there are other files with the extension .pal , and .sol.
These files comes from ATDI company.

I ever used a point file with the extension *.geo. I think you maybe can open it in notepad and extract its longitude, latitude, and height. Then import it into ARCMAP or ARCGIS's other model, and save it as shapefile version and add projection later. Actually many software can import ascii file and transfer it into vector file. As for *.img, it is the default file of Erdas. You can open it in Erdas's viewer, also you can transfer it into GeoTiff or other raster version.

Chubbers thanks for the great link. I downloaded a few and didn't work so far ... but still looking.

Thanks YZT_CNG ..... The file is huge ! about 500MB !! I don't think I can extract what you said! ... I downloaded Erdas ... but it has some weird error related to the network where I work , I will try to solve it.

Hasan, I'm sure Erdas and arcmap both can open *.img raster file. *.img is the default file of erdas. I think something must be wrong with your erdas setup. If you give me an email, I'd like to tell you how to setup it in detail. In addition, I don't know why you cannot open *.geo in those software. If possible, you can email me a small file to take a test.

I've received an email from somebody who is not a member with some additional comments on this (ancient) thread:

I met a .img formatted file which is not an ERDAS IMAGINE file. Plus .sol and .pal files. The .img and .sol files seem to have a 1010 byte header to be skipped. Open the files in Textpad or Edxor and you'll see in the header the image size and number of cols & rows like this: 100.000000100.000000M___________________8541______11725. Import in Erdas as generic binary, unsigned 8 bit data.

In my case .img was a scanned map image, and .pal I guess is a Microsoft palette file used for making the colors for the land use classification .sol (=Scenario Overlay?) image.

Then the map coordinates etc. should be defined according to the header as well.

But there must be some more straightforward way too to handle that img version.
